To all whom t may concern Be it known that l, @airone lll. @sanannre9 acitizen ot the United States, residing; at Olean, in the county oitCattaraugus and State ot New York, have invented certain new and usefullrnprovenients in lllil'orlringg` Barrels7 oit which the 'following is aspecication This invention coinprehends generally improvements in oilpumps and more par ticularly relates to an improved working` barrel. v

lin seine of the working; barrels now on the market the bottoni oit theworlrinp; barrel proper is iitted with a standing` valve designed tocoact with a seat carried by the tubing;1 so that the upper part oli thebarrel proper occupies a standing position while a space is lett betweenthe barrel and the tubing ironi the top of the barrel body to the seatand into which space Vline sand closely packed binding; the workingbarrel to the tubing); so securely that it usually necessitates pulling`out the tubing as well as the rod and the working barrel, from the wellin order to put in new pumps or otherwise repair the working; barrel.

llt is the primary aim and object ci this invention therefore to providea working; barrel designed to coact with a seat pro vided in the tubing'so that the major portion ot the barrel will be suspended or hunrf,troni the seat, and admission oit oil and sand to the space between theworking1 barrel and tubing1 is prevented, thus preventing; binding),1 oithe worlrinp; barrel and the consequent ditliculty in eitt'ecting; itsreinoval 'from the tubing. A

Among the other aims and objects et this invention may be recited theprovision ot a device et the above mentioned character with a view tocoinpactness and wherein the number oit parts are comparatively tewu theconstruction simple, the cost oitproduction low and the efficiency high'lllhe improvements in the details, and in the arrangement oit partswill be apparent troni an inspection oil the accompanying; drawings, inconnection with the speciiic description hereinafter contained, andwherein the prcierred embodiment or the invention is disclosed tor thepurpose oit imparting; a l'nll anderstandinar oi the invention. i

Vlhe invention is clearly illustrated in the accompanying drawings, inwhich z-f .'Jpeciicaton of Letters Patent.

Figure l is a vertical central sectional view olthe improved device,

F 2 is an enlarged side elevational detail or a portion ot the devicewhen detachcd, and

3 is a. transverse section talren on line 3-3 ot Fig. 2.

Similar characters oi reference are einployed in all olf the abovedescribed views7 to indicate corresponding parts.

Reiter-rino; now, more particularly, to the accompanying drawings thereis illustrated sections land 2 ot the well tubing the adjacent ends ofwhich are joined by a couplinp,1 3, torn'iinpan interior annular seat 3awhile on this seat suspended within the tubing,` beneath the scat is theimproved working barrel designated in its entirety by the numeral 4l.

lin the present instance this worlring1 barrel consists ot a barrel ortubular body 5, the lower end oi which is iitted with a check valvewhich desirably consists oil an r-imteriorly` threaded tubular seatmember 'l' detachably engaged with the lower end ot' the body 5 andfitted on its upper edge with a crown or =guard El the latter acting; asa retainer vfor ball checks 9 which in turn coacts with the seat member'l in controlling the admission ot oil into the barrel body duringI theoperation ot the vertically reciprocable working; valve designated inits entirety by the numeral l oli a conventional eonstrnction andoperably connected with the valve stein or rod ll also arranged withinthe body or casingF 5.

llll'ith a view toward providingf the inin proved means -lor insuring1et the suspension oit the barrel body beneath the seat 3 so as to inconsequence prevent line sand troni entering1 the space between the workinp; barrel and tubinpI and thereby binding the worlrinpg barrel andinterfering; with an ed'ective operation thereoit there is provided animproved seat member generally designated by the immoral l2 including);a tubular body i3 the bore of which is disposed about the stein il andis oli a diameter agr-eater than the diameter olf said stem llO I 16, ofleather. The lower terminal of the seat member 12 is threaded as at18and fitted in a corresponding formed terminal of an improved tubularcouplingl member generally designated by the numeral 17 whichconstitutesa seat tor the lower-most ring 16 and is provided with arelatively large diameter bore, receiving` the stem 11. The lower edgeot the body 17 is reduced and' exteriorly threaded as at 20 and designedfor detachable engagement with the interior threads on the adjacentupper edge of the barrel body 5. In this connection it is .to beobserved that the lower edge'otl the coupling member 17 is reduced so asto limit the upward movement ot the working barrel 10.

In controlling the iow or passage of oil through the bore in the seatmember 12, the upper portion ot the body thereof is reduced and threadedas at 21 leaving a shoulder 22, while detachably connected to thethreaded reduced portion 21 and abutting the shoulde 22 is the lowerportion of a guard or crown 23 which coacts with the annular valve body2l slidably and snugly mounted about the stem 11 and designed to in turncoact with the upper` edge of the seat member which 'terms a seat 25therefor and prevent liquid trom flowing downwardly through the member12. The several rings 16 are coniined and clamped on the.` member 12between the upper terminal of the coupling member 17A and the crown 23.rIhe cylindrical casing of the guard or crown is providedwith a circularseries of vertically arranged slots 26 through which the oil assessubsequent to passing by the seat 25.

he Vouter surface of the casing` or body ot the guard or crown is formednear the upper edge with opposed pairs ot vertically arranged recesses27. Coat-.ting with these recesses is a top; nut 28, the tubularattaching body 29 of which is disposed about the f upper endfot the stem11 and is connected therewith as by a pin and in addition is externallythreaded and adapted to receive one end of the suspension rod tor theworking barrel. In the event of the separation of thisvrod, thebody 29is formed with a plurality of radial arms 31 from the terminals of whichdependlugs 32 which are designed tovengage the recesses 27 whereby thestem 11 andmember 28 are held against rotation during application oitthe rod to the member 28.

In use, assuming that the parts have been assembled in the manner shownand describedV and that the shoulder or .tapered body formedby the rings16 is engaged with the upper edge of the seat 3 so that the barrel body4 is suspended or hung therefrom, upon the downward stroke et the stem1l carrying the working barrel 10 oil standing in the barrel 5 above thevalve 9 will be forced through the working valve 10 and'upwardly throughthe bores ot the coupling` member 17 and the seat member 12 by the valve2l into the casing or tubing. On the reverse or upward stroke the ballcheck 9 will be raised, the working valve drawing` oil through thetubular seat member 7 into the tubular barrel body 5. Ot course thecheck valve 2-1 seats preventing` the oil which has been. elevated tothe upper portion ot the tubing `from passing downwardly through thebore ot the seat member. ils the tapered shoulder or body formed by therings 16 is seated on the seat- 3, oil carrying tine sand is preventedfrom passing by the same into the space between the working barrel andtubing and rendering removal ol the barrel dilicult. The particularadvantage resides in the positioning ot the body of the barrel insuspended position upon the main seat, as is apparent and in closing theupper portion of the tubing against admission of oil conveying sand.

It is believed in view ot the 'foregoing description that a furtherdetailed description of the operation of the invention is entirelyunnecessary. Likewise, it is believed that the advantages of theinvention will` be readily apparent.

Still further embodiments oit the invention than those herein especiallydefined may be resorted to as conditions or preference may dictate, asmay be in keeping with the hereto appended claim.

Having thus fully described the invention what is claimed as new anddesired. to be secured by Letters Patent, isz- A working barrel of thecharacter de scribed including a tubular body, a working valve operatingin the body, a stein connected with the working valve, a tubular seatingmember having its bore of greater diameter than the stem and arrangedabout the stem, rings arranged about the seating mem- `ber a-nd forminga tapering seating shoulder, a valve operating about the stem andcoacting with the upper edge of the seating member, a crown detachablyconnected with the upper edge of the seating member, a sub-connectioncarried by the upper end of the stem and designed for .interlockingengagement at times with the crown and a tubular coupling member havingits respective ends detachably connected to the upper edge ot' the bodyand to the lower portion of the seating member designed for connectingthe seating member to the body'and tor clamping the rings on the seatingmember, and an external tube receiving the tubular member having aninternally restricted portion engaging the seating` shoulder.

In testimony whereof I aliiX my signature hereto.
